Abstract

Generally, the rating of an electrical machine is determined by its thermal limits. Induction generator is majorly used in wind power plants, to determine the operating speed of the induction generator, which is based on the wind speed. Hence the frequency of the generated voltage and current is variable. This paper presents a nonlinear temperature controller to estimate the saturated/steady state stator winding temperature at different operating currents and frequencies. A digital temperature sensor is used to measure the saturated winding temperature of the transformer at different currents and frequencies. By using polynomial curve fitting technique a nonlinear controller is implemented based on the experimental results, which is further used to estimate the saturated winding temperature of induction generator at different loads and frequencies. This is justified, verified and validated by experimental results.
